The many fires burning throughout the state and region wreak havoc on air quality, especially in valleys like ours where the air can get trapped by pressure systems and hang around for a while.
We've got air quality alerts most days here. On this day, when Cathy and I and the hounds took a hike up in Orchard Gulch, the alert was orange.
It's nasty stuff. And while I've ignored the alerts in the past and gone about my riding/running/whatever, I've learned that inhaling this rate of particulate matter can really do some deep damage to your lungs.
So if you heed the warnings, it gets pretty tough to get the workouts in. And it looks nasty, too.
